Did you know that both magnetic and gravity surveys can be used for mineral exploration? They both use some common equipments but have different strength and weaknesses.

In magnetic surveys, special instruments are used to measure the strength of magnetic fields at various points. Gravity surveys also use precise instruments to measure the strength of gravity at various points. The later method is most effective at accurately spotting oil deposits. I read a blog regarding it in the website gemsys.ca . But if you have more points, can share it here. It is really a wide topic which need to be discussed.
